The current view-transitions-2 spec for @view-transition 'types' (https://drafts.csswg.org/css-view-transitions-2/#descdef-view-transition-types) doesn't seem to place any restrictions on the values of its <custom-ident> sub productions, but WPT seems to require that values that start with "-ua-" are invalid.
Is this condition just missing from the spec? Or is it specified elsewhere and I just don't have the full context?
